Identify the arrows that represent the process of cooling.
gas
liquid

Answers

Answer:

Liquid - Gas is Evaporation & Gas - Cooling is condensation

Explanation:

The given image shows the water cycle in the atmosphere and hydrosphere. The cooling occurs at the clouds by condensation the evaporated water vapor cools down and precipitate as water. Hence, the arrow to the water bodies from the clouds indicates cooling.

What is water cycle?

Water cycle is a geological process by which the water content is balanced between the atmosphere and hydrosphere. The heat radiated from the sun makes the water bodies warmer by convection.

The warm water starts to evaporate to the atmosphere. The water vapor reaches the clouds from there after some time the gas starts to cool down by condensation.

The condensed water then precipitates down as rain and fills the water bodies again. The cooling process thus takes place in between the clouds from gas state to liquid state.

The nuclear reaction could be controlled and maintained.

Answers

The nuclear reaction could be controlled and maintained.

Explanation:

People had initiated a self-sustaining nuclear reaction--and then stopped it. He had released the energy of the atom's nucleus and controlled that energy.

Fermi's achievement in setting off the first self-sustaining nuclear chain reaction from his design of an atomic pile led to a new Age of the Atom. The controlled release of nuclear energy was now a reality

Which of the following nonmetals can conduct electricity relatively well
sulfur
iodine
carbon
bromine

Answers

It’s suppose to be graphite. But I’ll go for Carbon.

Carbon is a nonmetal that can conduct electricity relatively well. Therefore, option (D) is correct.

What is carbon?

Carbon is an element that belongs to the 14th period in the modern periodic table. The atomic number and atomic mass of carbon are 6 and 12.01 g/mol. Carbon is a nonmetal and tetravalent as it contains 4 electrons in its valence shell.

Carbon is short-lived but it can be stabilized by its allotropic forms. Carbon has three allotropes which are diamond, graphite, and fullerene. The properties of allotropes of carbon are different because of the different arrangements of carbon atoms.

In graphite, the carbon atoms are arranged in layers and are joined together. The links between the layers of the carbon atoms are weak but links between the carbon atoms in the layer are strong. The layers are slippery in nature which makes graphite soft.

Graphite is the only nonmetal that can conduct electricity and is a good conductor of electricity.

What type of bonds typically form between two nonmetal atoms?

Answers

Answer:

Covalent Bonds

A covalent bond is formed between two non-metals that have similar electronegativities. Neither atom is "strong" enough to attract electrons from the other. For stabilization, they share their electrons from outer molecular orbit with others

Answer:

Covalent bonds form between two non-metal atoms.

Explanation:

Nonpolar covalent bonds form when the electronegativity values are very similar, while polar covalent bonds form when the electronegativity values are a little further apart. If the electronegativity values of two atoms are different, ionic bonds are formed.

The pressure exerted by a gas on its container is directly proportional to ________. Group of answer choices the volume of the container the mass of the individual gas molecules the Celsius temperature of the gas the number of molecules of gas in the sample the Fahrenheit temperature of the gas

Answers

The pressure exerted by a gas on its container is directly proportional to the mass of the individual gas molecules.

Gas law states that the pressure exerted by a gas on its container is directly proportional to its absolute temperature (Kelvin temperature) and number of moles of the gas.

PV = nRT

where;

P is the pressure of the gasV is the volume of the gasR is the gas constantT is the absolute temperature of the gasn is number of gas moles

[tex]number \ of \ moles = \frac{\ reacting \ mass \ of \ individual \ gas}{molecular \ mass}= \frac{m}{M}[/tex]

[tex]PV = \frac{m}{M} RT[/tex]

Thus, the pressure exerted by a gas on its container is directly proportional to the mass of the individual gas molecules.

Answers

One of the first major scientific discoveries of the Renaissance was made by a polish mathematician and astronomer, Nicolaus Copernicus who introduced the heliocentric theory.

Nicolaus Copernicus (1473-1543) was born in Torun, Poland, and he introduced a book called De revolutionibus orbium coelestium (On the Revolutions of the Heavenly Spheres) in 1543, where he stated that:

"All the spheres (planets and moons) revolve around the sun as their midpoint; therefore, the sun is the center of the universe."

At that time, the Earth was considered the center of the Universe, according to Aristotle (384-322 BC), synthesized in the Ptolemy's geocentric theory appeared in The Almagest (140 AD).

Copernicus generated controversy, mostly among the clergy and scientists, and he wrote in his book that his main intention was to propose some changes to the Ptolemy's geocentric theory that better explained planetary motion but without trying to refute it at all.

How are radiation levels kept in balance?

Outgoing

Earth emits


Back toward the sun in the form of



Answers

Answer:

Explanation:We known that Earths energy machine is driven by sunlight which acts as fuel for this machine and to strike a balance between outgoing long wave radiation and short wave radiation there are many factors which are involved in this process.Sun emits this energy in the form of short wave radiation because of the huge energy it has and short wave radiation are higher in energy.Hence, they reach the earth surface mostly as visible and UV rays.After reaching the earths surface what happens with these rays is that they get absorbed by the clouds and other constituents of Earth.

Now, this energy needs to be emitted back in to space in order to balance out the energy budget of earth and that is why this energy is emitted back as long wave radiation which have less energy and also earth has less energy unlike the sun.Loss of this energy is essential as Earth looses most of its energy through this and results in cooling.But when this OLR decreases it should be a cause of concern for us.

This imbalance is caused by a wide range of different human induced activities which has a cumulative effect on the temperature of earth.These activities gives rise to a huge gain in the CO2 concentration which is why this word has gain so much popularity and a cause of widespread concern for us.At community level we contribute to this heating by increasing usage of personal automobiles rather than going for public transport , advancement in technology has greatly changed our lifestyles making it more simpler and easier but this demands more energy consumption.Landscape changes are one of the most important because its taking place at a faster rate.Most of the land being cleared off to built new houses which means clearing off the existing vegetation which leads to temperature rise.Setting up of Industry depending on its type can reduce the amount of OLR escaping the surface by introducing more amount of GHGs in to the atmosphere.

Its these small communities which add up to become the entire human population causing a massive damage and hence at community level if people realize and take necessary steps things will start to change.
